BUFFALO, NEW YORK.

To all whom it may concern:

Be it known that I, Eucimn Monnau, a citizen of the Republic of' France residing at New York, in the county of' N ew Yor and State of New York, have invented a new and useful Improvement in Apparatus for Feedin or Discharging Grain, &c., of

which the ollowing is a specification.

This invention relates to the mechanisms which are em loyed in connection with vacuum ain riers and similar apparatus for feeding the grain or other material to be dried or treated chamber and removing it therefrom without interfering with the maintenance of the vacuum therein. Feeding and discharging mechanisms of this general character comprise, as shown, for instance, in Patent No. 748,414, Dec. 29, 1903, to Emil Passburg, a'receiving chamber or receptacle for the material, an inlet valve which controls the admission of the material to this receptacle, and an outlet valve which controls the exit of the material therefrom. The valves shown for that I purpose in said patent are rotary disks, each having a pocket for receiving the material and conveying it from the inlet opening, through which the material passes to the valve, to

another opening through which the Ina-- terial esca es from the valve.

The ob ect of this invention is to promechanisms of this general character in w 'ch swinging or pivoted valves are employed, whereby the frictional resistance of the valves and the power required for actuating the apparatus are greatl reduced and the apparatus is rendere more etficient and satisfactory in its operation.

In the-accompanying drawings, consisting of five sheets: Figure 1 is an elevation, partly in section, of a grain drying apparatus embod g this invention. Fig. 2 is a sectional e evation of the feeding or discharging apparatus, on an enlarged scale.

Fig. 3 is a sectional elevation at right angles to Fig. 2, in line 3-3, Fig. 2. Fig.

chamberb or tanks arranged one above the other and constructed in any suitable manner and connected with any suitable exhaust apparatus for maintainmg the desired vacuum therein. The upper tank A receives the grain at one end from the feeding appa- 7o ratus C and delivers the grain at its opposite end to the lower tank B which in turn delivers the grain at its opposite end to the discharging apparatus D. The feeding apparatus and the discharge apparatus are alike in construction but'difier in their relation to the tanks, the feeding apparatus having its inlet open to the atmosphere and its outlet connected with the exhausted tank,

while the discharging apparatus has its inlet connected with the exhausted tank and its outlet open to the atmosphere. The drying or treating apparatus may comprise a' single tank as may be making the connections the feeding apparaor a number'of connected tanks,

tus and. the discharging apparatus may be arranged one above the other, as shown.

Each apparatus for feeding or discharging the grain is constructed as follows: 10

re resents an inlet trough having a semic indrical bottom provided on opposite sides of its longitudinal center line with feed openings 11, 12, which are alternately opened and closed by a rock valve 13 secured to a rock shaft 14. This trough receives the rain in the case of the feedlng-apparatus from afeed spout, (not shown), and in the case of the discharge apparatus 1) from the discharge opening of the vacuum tank.

15, 16, represent two preliminary receiving or measuring chambers arranged respectively below the feed openings 11, 12, and separated by a partition 17' which is arranged between these openings.

extend in the same so high as to interfere with the free movement of the valve. The

outlet openings

22, 23, of the main chambers are controlled by similar swinging or

pivotal valves

28, 29, mounted on

transverse shafts

30, 31, respectively, and arranged in a chamber 32 beneath these openings. In the case of a feeding mechanism this chamber opens into the inlet opening of the vacuum tank and in the case of a discharge mechanism it opens into a discharge spout or conveyer which is open to the atmosphere. The main receiving chamber 20 is provided with a suction opening 33 which is arranged in the side of the chamber and is controlled bya valve 34 arranged in a chamber 35 connected with the exhaust apparatus by a pipe 36, so that the valve chamber 35 is exhausted and the receiving chamber 30 is placed in communication with the exhaust by opening the valve 34. The main receiving chamber 21 is similarly provided with a suction opening 37 controlled by a valve 38 in a chamber 39 having an exhaust pipe or passage 40. 1

The

exhaust valves

34 and 38 are actuated respectively by

arms

41, 42, on transverse shafts '43, 44.

The operation of this'apparatus is as 'fol lows: Assuming the feed valve 13 to stand in the position shown in Fig. 2, in which this valye uncovers the feed opening 11 and cov- N ers the feed opening 12, the preliminary chamber 15 is in communication with the feed trough 10 and receives grain therefrom until it is filled, the discharge opening 18 in the bottom of the preliminary chamber being closed'by the valve 24. The suction valve 34 of the chamber 20 'is closed and the discharge valve 28 is open, so that the grain passes from the chamber 20 into the bottom chamber 32 and thence to the vacuum tank, in the case of a feeding apparatus, or to the discharge spout in the case of a discharging apparatus. At the same time the reliminary chamber 16 is cut off from the sad trough 10 by the feed valve 13 the grain in the preliminary .chamber 16 is discharged through the opening 19 into the main chamber 21, the upper valve 25 being open and the lower valve 29 closed and the exhaust valve 38 bein also closed. The feed valve 13 is next The. ower valve 28 of the chamber 20 is closed, the upper valve 24 .of this chamber is opened and the grain flows from the prelimmary chamber 15 into'the main chamber 20. The upper valve 24 is then closed and the exhaust valve 34 opened, whereby the main chamber 20 is placed in communication with the exhaust and the air is removed, which has entered with the grain from thepreliminary chamber, in the case of a feedmg apparatus. The exhaust valve is then closed and the dischar e valve 28 opened, whereby the giainis ischarged from the chamber 20 into the vacuum tank. In the ifted so as to close v the o ning 11 and uncover the opening 12.

case of a discharging a paratus, the air enhave been closed, thereby preventing this air from entering the vacuum tank.

4 The feed valve may be a rocking valve, as shown, or of any other suitableconstruction. The valve operates mainly as a cut-ofi for breaking the communication between the preliminary and the main receiving chambers and can work freely without forming an air-tight closure.

By duplicating the preliminary and main recelving chambers and accessories and operating the two sets alternately, a practically continuous operation of the apparatus is produced. A single set may be employed, however, if desired.

The pivoted or swinging valves which are employed in connection with each main receiving chamber move freely in the chambers in which they are arranged, their movement upwardly to their seats and down-.

wardly from their seats is not retarded or rendered difiicult by grain, dust or it which may adhere to the valves and t ey seat themselves tightly when closed.

The mechanism for actuating the different valves at the proper time may be of any suitable construction, that which is shown in the drawings being constructed as follows: 49 represents the main drive shaft of the valve mechanism arranged horizontally and driven by means of a pulley 50.- This shaft is provlded with a pinion 51 meshing with a gear wheel 52 on a horizontal counter shaft 53 carrying a pinion 54. The latter meshes with a gear wheel 55 on a horizontal shaft 56

carryingtwo cam disks

57 and 58. The cam disk 57 actuates an arm 59 on a rock shaft 60 carrying

arms

61 and 62. The arm 61 is connected b a rod 63 with an arm 64 on the shaft 27 o the pivoted valve 25, while the arm 62 is connected by arod 65 chamber,

with an arm 66 on the shaft-43 of the exhaust valve 34. The cam disk 58 actuates an arm 67 on a rock shaft 68 carrying an arm 69 which is connected by a rod 70 with an arm 71 on the shaft 31 of the lower pivoted valve 29. The gear wheel 55 on the rotary shaft 56 meshes with a gear wheel 72 on a horizontal shaft 73 which is provided with a cam disk 74 which actuates the feed valve 13 by means of a rod '75 and arm 76. The gear wheel 72 on the shaft 7 3 meshes with a gear wheel 77 on a shaft 78 carrying

cam disks

79 and 80. The cam disk 7 9 actuates an arm 81 on a rock shaft 82 provided with an arm 83 connected by a rod 84 with an arm 85 on the shaft 30 of the lower pivoted valve 28. The cam disk 80 actuates a rock arm 86 on a rock shaft 87 which is provided with an arm 88 connected by a rod 89 with an arm 90 on the shaft 26 of the upper pivoted valve 24. The exhaust valve 38 is actuated from the cam disk 79 and rock shaft 82 by means of an arm 91 on said shaft which is connected by a rod 92 with an arm 93 on the shaft 44 of this valve. The lower end of the rod 75 actuated by the cam disk 74 may be guided by a rock arm 94 loosely mounted on the rock shaft 87. The

exhaust valves

34, 38 have their

stems

100, 101, guided in frames 102, 103, and provided with projections 104, 105, which are engaged by the

rock arms

41, 42, respectively.
